per this thread: Accuracy on 4x8 area ,
@rerskins notes the fact (now obvious after some thought) that MaslowCNC cuts better vertical lines on the ‘upstroke’ and postulates that we can optimize Fusion360 preferences to minimize machine motions that are more problematic.
(ie: downward cuts, on the outside of the machine boundaries, where sled friction and gravity and chain sag all work against the direction of cut.)
I’m sure that (given the sheer number of different CAM machines and operations Fusion360 accounts for) there’s some amount of control available to set this, but I haven’t yet found where in Fusion360 one would set these preferences, so keep an eye out!
cheers,
